GSoC 2024 Project Idea 9.1 Efficient app-based measurement of visual functions in infants and young children (350 h)

Accurate and efficient measurement of visual function is difficult in infants and young children because of limited cooperation, inability to provide cognitive verbal responses and lack of efficient behavioural methods. This is important in the clinical and research context where detection and treatment of eye conditions in infancy is dependent on measurement of visual function. Visual deprivation in infants disrupts normal visual development and affects multiple visual functions that are important in visually guided behaviors in everyday life such as contrast sensitivity, motion perception, contour integration, and face recognition. At present there are no reliable automated objective methods for measuring visual functions in infants and young children below the age of 3 years.

In this AI for health project, that continues work from GSoC 2022 and GSoC 2023, we will address these limitations by developing a deep-learning based eye-tracker to test infant visual function by automatic monitoring of their eye-movements. Previous projects made progress towards developing an eye-tracker module that can work both with software-based and hardware-based eye-trackers and with developing a visual stimulus presentation module. Both these modules will be developed further in this year’s GSoC so that a full proof of concept can be developed. The project involves a) the development of an application with a suite of visual stimuli and analytical procedures to probe multiple visual functions; b) testing and further developing a deep-learning based infant eye-tracker and c) developing a GUI and controller that holds the display, eye-tracking and analysis components together.

Hello Sir,
My name is Mohamed Atef. I am an Egyptian senior AI student. I am interested in your project and I took a quick look at the GitHub repository, however, I have some questions:
1 - Did you use a specific dataset for training the tracking model?
2 - What advancements do you want in the project in detail?
3 - I did not understand how a hardware device will be integrated, could you elaborate?
I also want to know more about the project to conduct more research, so any guidelines will be helpful.
Thanks in advance.

Hi @suresh.krishna @arvindchandna,

I am Dhruvanshu Joshi, a pre final year student at VJTI. I am a computer vision and deep learning enthusiast. I have tried to use these skills to solve real world complex problems through my projects like Pothole detection which uses computer vision and depth estimation to detect road potholes. I also am the global runner up of OpenCV Spatial AI competition, 2022. I have spent quite some time as an open source contributor and worked as a open source summer intern at PyMC during the summer of 2023. I am interested in working on the project titled “ Efficient app-based measurement of visual functions in infants and young children (350 h)” as a part of GSOC, 2024.

I have been through the code base and built the project locally including the necessary psychopy installation. I see that the original implementation is based on icatcher+ which is trained on the Lookit dataset. I believe that integration of api developed by Ioannis Valasakis with the current implementation would be a valid next step to replace the need for keyboard inputs in the experiments.

It would be really helpful if you can guide me to some task/issue that I can solve in order to contribute to this project. I am attaching my resume here for your reference.

Yours Sincerely,
Dhruvanshu Joshi

Hello !!
My name is Tvisha Vedant and I am currently a second-year B.Tech Computer Science student at Veermata Jijabai Technological Institute,Mumbai
I have a strong background in various areas of computer science, including natural language processing (NLP), image processing , web development,Pytorch , using libraries like numpy/pandas and version control with Git/GitHub. I had contributed in building a web-app which controlled the music volume and playback using gestures using Media-pipe.I have worked extensively with LLMS like langchain, Transformer architecture, and NLP, which I applied in developing a healthcare chatbot(using the Llama model from hugging face after testing a lot many models).
Having gone through the eye tracking projects of GSOC’22 and GSOC’23 I would like to contribute to its extention under GSOC’24. I have started building the repo locally.
I am new to the world of open source with just a few month’s experience but the entire concept and setting of open source contributions appeals me !!
Looking forward to collaborating with you.

Do share any updates regarding the tasks to be performed for GSOC’24

@Dhruvanshu_Joshi @Mohamed1 @Tvisha_Vedant - thanks for the interest. The first step is to go through the code-base, learn how to use Psychopy and understand how the eye-tracker component is working. The possible extensions include improving the eye-tracker quality, increasing the library of visual stimuli that can be generated, developing a functional and well-designed GUI that interfaces with the eye-tracker and stimulus components, etc. Additional extensions will be posted here in a week.

Feel free to post here if you have any issues. Please first do some homework and read up, and only ask after you have put in some work and thought - and please describe in detail what you did. It is important that you do this before you ask for help - we have busy day-jobs and we are helping many of you at the same time.

We have compiled a list of feature enhancements below. In the interim, get familiar with the code-base and test it out yourself to better understand the feature upgrades. Feel free to reach out to @soham_mulye , if you have any issues. Please think before you reach out though, do some homework and read up, and only ask after you have put in some work and thought - and please describe in detail what you did. It is important that you do this before you ask for help - we have busy day-jobs and we are helping many of you at the same time

Some example features to be added to the project:

  1. Enhance the GUI to offer a more interactive and user-friendly experience.
  2. Change the stimuli to an attractive cartoon character and use an additional auditory cue with each change whenever possible to keep infants engaged in the experiments.
  3. Also allow smooth flow of stimuli across the screen from one point to another.
  4. Add more stimulus classes (needs Psychopy knowledge).
  5. Test the software - create an installation routine that works more reliably in case bugs are found.
  6. The deep learning model’s current limitation is that it only detects gaze direction in either left or right directions, so it cannot be utilised in studies with stimuli in all four hemispheres. Fix the issue.
  7. Provide functionality for easy integration of eye tracking hardware devices such as Tobii eye trackers, allowing anyone having the hardware to run the programme.

Hi @suresh.krishna @arvindchandna ,

I am Sarthak Puri, a B.Tech Computer Science student at Chandigarh University. I have expertise in machine learning, deep learning and app development and find this project align with my skills and experience till now so well that it feels as though I was destined to work on it. Can you provide me with your email, I would like to connect with you directly and discuss one key aspect of this project before drafting the proposal.

Thanks & Regards

@Sarthakpurii you can direct message me here

At the current point of time, GUI has been implemented with TkInter with which I am proficient as well, but to create a comprehensive and user-friendly application, Flutter will be the best choice given its cross platform characteristic as well. Also integrating deep learning models to flutter apps is also not a puzzling task, with the help of tensorflow lite.

Before proceeding with drafting my proposal, I wanted to discuss with you and understand your views on incorporating Flutter for the app development part of this project.

sure. no problem with proposing to use flutter

That’s really good to hear. I will continue to work on my proposal and having it reviewed by you before submitting it would be immensely beneficial.

And I couldn’t properly introduce myself earlier which I thought I will be doing on mail

So I am Sarthak Puri, a B.Tech Computer Science student at Chandigarh University. I have expertise in machine learning, deep learning and app development with flutter. I did an internship at SHMT as ML engineer which also focuses on the intersection of technology and healthcare. I have done many similar projects like emotion detection etc in the field of computer vision which stole my attention to contribute to this project.

I look forward to the possibility of contributing to this meaningful project under your guidance. Thank you for considering my inquiry.
